We're dividing 631691 by 59 
The aim is to understand the frequency of 59 in 631691.

Advancing to step 1:
When dividing 6 by 59, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 59

Let's proceed to step 2:
63 divided by 59 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 59 from 63 leaves us with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 59

Moving on to step 3:
When dividing 41 by 59, we get 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 41 and we're left with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 59

Going ahead to step 4:
59 can be fit into 416 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 3 after subtracting 413 from 416.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 59

On to step 5:
If we divide 39 by 59, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 59

On to step 6:
59 goes into 391 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 10706.0
Subtracting 354 from 391 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 59, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 10706.6
If we take 354 away from 370, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
The number 59 fits into 160 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 10706.62
If we subtract 118 from 160, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
59 can be fit into 420 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 10706.627
Subtract 413 from 420 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
59 can be fit into 70 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 10706.6271
If we subtract 59 from 70, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 59, we get 1 and a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 10706.62711
Deduct 59 from 110 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 10706.62711, with a leftover of 5.1e-05.
